I-430 forms the western bypass of Little Rock, the capital of Arkansas. The highway runs north-south along the west side of town, from I-30 to I-40. The entire highway has 2×3 lanes, has a junction halfway with Interstate 630 and crosses the Arkansas River via a bridge. It is the westernmost bridge over the river at Little Rock.

Early plans for the Interstate Highway system already envisioned a western bypass of Little Rock connecting I-30 to I-40. The highway was built a little later than the I-30 and I-40, and was opened to traffic in 1975-1976.
Between 2009 and 2015, the ‘Big Rock Interchange’ between I-430 and I-630 was reconstructed. Originally a cloverleaf with no shunting lanes, it features a dive-under for traffic from Financial Center Parkway to I-630, as well as four flyovers for traffic between the two freeways. The work was completed on 8 July 2015. In 2015-2016, the flyovers of the interchange with I-40 were replaced by two-lane flyovers. This coincided with the widening of I-40 between Maumelle and Little Rock.
In October 2019, plans were announced for a rush hour lane on the bridge over the Arkansas River.

The highway handles quite a bit of traffic, usually between 75,000 and 96,000 vehicles per day. Because 2×3 lanes are available, this does not lead to congestion.

Interstate 440 in Arkansas
Interstate 440 or I -440 is an Interstate Highway in the U.S. state of Arkansas. The highway forms the eastern bypass of the state capital Little Rock, and runs from I-30 to I-40. The route is 16 kilometers long.
The highway begins on the south side of Little Rock at a major interchange with Interstate 30 and Interstate 530. I-30 comes here from Dallas and Texarkana, turning north here, while I-440 continues straight east. Heading south, I-530 heads toward Pine Bluff. I-440 has 2×3 lanes here and serves the city’s airport. On the east side of Little Rock, the highway crosses the 700-foot-wide Arkansas River with a bridge, then turns north. I-440 then ends at the interchange with Interstate 40. SR-440 then continues straight north, while I-40 from Little Rock to Memphis goes east.
I-440 was the last Interstate Highway built at Little Rock. It is primarily intended as a bypass for through east-west traffic from I-30 to I-40, so that the truck flow from Dallas to Memphis does not have to go through downtown. I-440 opened in two phases in 1982 and 1983, the last of which opened the bridge over the Arkansas River.
The extension, State Route 440 from I-40 north to US 67, was under construction around 1994 to State Route 161, this section likely opened around 1996, although the interchange with US 67 was not opened until 2003.

|Exit 5 Fourche Dam Pike||Exit 7 US 165||3 km||1983|
The I-440 may in the future together with the Interstate 430 form a complete ring around Little Rock, of which the SR-440 was already built in 2003.
I-440 is not very busy, with between 72,000 and 48,000 vehicles per day. Because 2×3 lanes are available, this does not lead to congestion.
